JOINT FOR RAILROAD-RAILS.

SPECIFICATION forming part of Letters Patent No. 586,309, dated July 13,1897.

Application filed February 4, 1897. Serial No. 621,982. (No model.)

To all whom it nmy concern:

Be it known that I, FREDERICK A. HUMME, a resident of Ohristy Park, inthe county of Allegheny and State of Pennsylvania, have invented a newand useful Improvement in Joints for Railroad-Rails; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof.

Myinvention relates to joints for railwayrails.

The object of my invention is to provide a joint for railway-rails inwhich the use of fish-plates and bolts are dispensed with, the adjoiningends of the rails being so interlocked as to form of themselves a verysecure connection, while at the same time the end of one rail will notrise or fall below the level of the end of the adjoining rail, whereby asmooth and even joint is insured.

My invention comprises, generally stated, a rail having a web at one endthereof with a seat formed therein, said web extending beyond the headand foot of the rail, and a rail having its web and foot extendingbeyond its head, the web of said last-mentioned rail entering said seatin the web of the firstmentioned rail, the heads and feet of the railsabutting and the enlarged web of the first-mentioned rail extendingbeyond the line dividing the heads of said rails and filling the spacein said last-mentioned rail between its head and foot.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure lis a perspective view of the adjoining ends of railsconstructed according to my invention ready to be connected. Fig. 2 is aside view of the rails connected. Fig. 3 is a cross-section on the line3 3, Fig. 2.

Like letters indicate like parts in each of the figures.

The rail A may be an ordinary T-rail having the head 6, web 0, and thefoot d. The web 0 is enlarged at'the end of the rail, as at e. A seat orrecess f is formed in the enlarged web e. This web 6 extends beyond thehead I) and foot (Z and has the beveled joining T-rail B. This rail Bhas the head "I,

web It, and foot Z. The web It and foot Z entend beyond the head i.

To make the joint, the web 70 of the rail B is inserted in the seat f ofthe web 6 of the rail A, said web 70 being adapted to fit snuglytherein. In case the seat f is not of sufficient height to receive theweb 7:; a groove m may be formed in the head I) of the rail A. The webis enters the seat f until the head 5 comes in contact with the head iand the foot d comes in contact with the foot Z. With the parts of therails in this position, as shown in Fig. 2, the web 6 will extend beyondthe line dividing the heads b and i, and the beveled edges g g of saidweb will be in contact with the beveled faces h h, respectively, of thehead and foot of the rail B. By this construction the ends of the railsare so interlocked that any tendency on the part of either of-theadjoining ends to be raised or depressed by the action of the carstraveling thereon will be resisted by the other. This is due to the factthat the web e extends beyond the dividing-line of the rails. If thereis any strain tending to raise the end of the rail A, adjoining the railB, the web 6 being under the head of the rail B prevents any upwardmovement on the part of the rail A. Furthermore, the web 2 supports thehead i of the rail B.

The beveled edges 9 engaging with the beveled faces h of the head of therail B tend to hold said head against lateral movement and at the sametime a more secure joint is obtained.

By my invention I provide a joint which is very secure and yet one inwhich the rails are free to expand or contract longitudinally. The headsof the rails where they meet present an even smooth surface which willprevent the severe jars and strains to which the rolling-stock ofrailways is subjected, due to the unevenness at the rail-joints.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

A joint for railway-rails consisting of a rail having a Web extendingbeyond the head andfoot thereof, said Web having a seat formed therein,and a rail having its Web and foot extending beyond the head, said Webentering the seat in said first-mentioned rail, and the Web of saidfirst-mentioned rail extending beyond the line dividing the heads ofsaid rails, substantially as set forth.

In testimony whereof I, the said FREDERICK A. HUMME, have hereunto setmy hand.

FREDERICK A. I-IUMME.
